v6 v7 37 37 == Overview == 38 38 39 This page describes the recommended implementation of the analysis step of local filters with OMI using the PDAFlocal interface that was introduced with PDAF V2.3. The older approach calling PDAFomi_assimilate_ local or PDAFomi_put_state_localis documented on the page on [wiki:ImplementAnalysis_3DEnVar_untilPDAF221 Implementing the Analysis Step for 3D Ensemble Var with OMI without PDAFlocal (until V2.2.1 of PDAF)].39 This page describes the recommended implementation of the analysis step of local filters with OMI using the PDAFlocal interface that was introduced with PDAF V2.3.
